The Sierra Designs Convert 3 is a freestanding three-person tent that’s strong enough for four season winter camping and backpacking, but can also re-configured for three season use in less demanding conditions. It has a large main compartment and two vestibules, which make it a spacious, but lightweight winter tent with plenty of covered gear storage. Weighing in at 6 lbs 8 oz, fully configured, there are a number of different ways to configure the tent based on your needs. For example, you can remove the front vestibule to bring the tent weight down to 5 lbs 6 oz, making it easier to carry on winter backpacking trips. In dry desert environments, you even leave the rain fly and front vestibule at home and reduce the tent weight to 3 lbs 10 oz. The bottom line is that you get a lot of tent for your money with the Convert 3.
Note: Previous versions of the Convert 2 and Convert 3 are significantly different from the current Convert models in styling, design, and architecture. You can tell them apart by their colors: the newest Convert 2 and Convert 3 tents have a blue and yellow fly, while older model Converts are all yellow. Retailers aren’t always good at updating their product listings, so it’s important to know how to tell them apart.

The Convert 3 is a tunnel tent with two end vestibules. This design provides occupants with near vertical sidewalls and more headroom than a wedge-shaped tent with steeply angled sidewalls. The Convert 3 is also freestanding, which makes it much easier to set up on snow and sandy soil because the tent is self supporting. You’ll still want to stake out the tent when it’s erected to fully expand its interior and anchor it against the wind. This is one of the chief advantages of a freestanding tent in winter conditions, because you don’t have to wait for snow stakes, also called deadmen, to freeze in place before you can set up the tent. This lets you get in the tent more quickly and change out of wet or damp baselayers, so you can warm up.
Having two vestibules and two doors is a huge luxury on a winter tent, even more so since the Convert is so light weight. Having a front door and back door also make it easier for occupants to come and go at night, while the vestibules add significant additional covered storage, close to 75% more, by volume. For instance, the main part of the Convert 3 where people sleep has 40 cubic feet of room, while the front vestibule adds 19.6 cubic feet, and the rear vestibule adds 9.4 cubic feet. That added space provides valuable room for gear storage and even cooking or melting snow, in challenging weather conditions.
Pitching the Tent
Setting up the Convert 3 is fairly easy, despite its large footprint, and one person can pitch the tent by themselves in fair conditions. Two people are needed if it’s windy, raining, or snowing because the tent body and fly can become large sails if they catch the wind. The only really awkward thing about the setup process is wrestling with the the long ridge pole which is connected by hubs to two perpendicular poles for the front and rear ends. Once the poles have been anchored into their color-coded corner connectors, it’s a simple matter of inserting the middle support pole, walking around the tent, and clipping all of the inner tent hooks to the pole structure.
The fly is then draped over the pole structure, attached to the short awning overhangs over the front and rear doors, and then attached to the corner and side pole feet. The fly’s guy-out points have line-loc tensioners, but they’re difficult to tension when the guy line cordage is wet and frozen. This can require that you remove your gloves to fiddle with them, which isn’t optimal in winter, because wet hands can quickly become frost nip or worse.
You can pack the tent away with the front vestibule pre-attached or zip it to the main tent in camp. It has its own pole and a side door. I find it convenient to dig out half of the vestibule in snow because it makes it easier to get into and out of the tent, while still providing a place to store backpacks under cover. If you decide not to use the front vestibule. the front door of the inner tent is waterproof and protected overhead by a short awning.
The rear vestibule is smaller that the front vestibule, but provides a second convenient exit point or gear storage area for tent occupants. This vestibule is permanently part of the rain fly and not an optional add-on.
While the vestibules add a considerable amount of volume and external storage to the Convert 3, the inner tent width is snug for three people. While there is plenty of interior headroom (45″) and enough length in the inner tent for tall people to stretch out (84″), the living compartment is only 69″ wide at the front door, tapering to 59″ wide in the rear. This makes it difficult to use wider 25″ sleeping pads or exit the rear doors at night without disturbing other tent mates. If you only have two people in the Convert 3, it is a palace, but adding a middle third person is a much tighter fit.
That middle person is also at a disadvantage from a storage standpoint. While there are inner pockets for storage of smaller items on the sidewalls of the tent, the middle person doesn’t have anyplace to put their smaller items. A small gear loft or overhead pocket would be welcome addition for the person sleeping in the middle of the tent. Winter nights are really long and it’s nice to be able to stash your littles (eye glasses, phone, kindle, etc) where they are easy to reach and won’t accidentally be crushed.
The front and rear doors of the Convert have a layer of mesh covered by solid fabric panels that can be zippered closed over it. When the fabric panels are unzipped, there’s good airflow through ends of the tent. But the use of the front vestibule significantly compromises airflow, which can lead to internal condensation in winter, particularly when you have three occupants (exhaling water vapor all night).

The Sierra Designs Convert 3 is a freestanding, double-wall tent designed for four season use by up to three people. It is lightweight and spacious, with front and rear doors, a permanent rear vestibule and an optional front vestibule. Set up is easy and the tent packs up surprisingly small, making it easy to backpack into more remote locations. While the tent can house up to three occupants, I think it’s best used by two people who want more space than you normally find in a confining winter tent, or who want to bring a canine companion along. While this review has concentrated on winter use, the Convert 3 will also make a comfortable tent for warmer three season use without the front vestibule.
